I'm looking to switch my gamer picture to something rare. I like the zero hour gamer picture and I hear that these are on memory units that were handed out at the Zero Hour event. I've been looking on ebay to see if there are any of there memory units up for auction. Is it possible to get the gamer picture off of one of these memory units, if it is already in use by someone else or used by them in the past? Can a memory unit's gamer picture be on multiple accounts? If you have one of these from Zero Hour please tell me what you can about it, thanks.
